The Boston Globe reports that Police Superintendent Daniel P. Linskey patrolled the parade route in South Boston ahead of the first procession on Sunday. He sniffed beverage cups for alcohol and pulled beer cans from backpacks.

Officers followed Linskey, writing citations for those caught drinking on the street.

Boston Police issued 336 citations for public drinking and made 26 arrests primarily for disorderly conduct.

Linskey said that for the most part, the parade drew a responsible crowd.
